1.0.0 was never an intentional release and the nim-eth repo is not yet
stable in terms of API, thus we start at 0.5.0 and go from there for the
first tagged release.
Most of the eth code in this repo now is aligned with various specs
meaning that most API can be considered "mostly" stable, but there are
still aspects being worked on as well as a potential future
reorganisation of the code turning nim-eth into a more "pure"
spec-driven core ethereum infrastructure repo, removing in the process
application-level stuff that happens to be common between nimbus-eth1
and eth2 and ended up in here for convenience.
* cleanup macros
* add test cases and fix counting function
* add check statements
* remove deprecated support for Option
* replace some logic
* remove debug print
Since these types were written, we've gained an executable spec:
https://github.com/ethereum/execution-specs
This PR aligns some of the types we use with this spec to simplify
comparisons and cross-referencing.
Using a `distinct` type is a tradeoff between nim ergonomics, type
safety and the ability to work around nim quirks and stdlib weaknesses.
In particular, it allows us to overload common functions such as `hash`
with correct and performant versions as well as maintain control over
string conversions etc at the cost of a little bit of ceremony when
instantiating them.
Apart from distinct byte types, `Hash32`, is introduced in lieu of the
existing `Hash256`, again aligning this commonly used type with the spec
which picks bytes rather than bits in the name.
